TIMSS

GitHub document

This is an R Markdown format used for publishing markdown documents to GitHub. When you click the Knit button all R code chunks are run and a markdown file (.md) suitable for publishing to GitHub is generated.

Including Code

You can include R code in the document as follows:

fL <- "TIMSSmath.txt"
dta <- read.table(fL, header=T, fileEncoding="big5")
# write.csv(dta, 'data/TIMSSmath.txt', quote=FALSE, row.names = FALSE)

Including Plots

You can also embed plots, for example:

plot(dta[, c(4,8)], bty='n', cex=.2, family="Kaiti TC")

Note that the echo = FALSE parameter could be added to the code chunk to prevent printing of the R code that generated the plot.
